Abstract: A pre-fabricated semi-spherical dome and a spherical structure which are formed in combination of pentagons and hexagons; wherein the semi-spherical dome is built by assembling 6 sets of pentagonal modular assemblies (2), each of which is a structure assembled by coupling 6 outer/inner struts (5)(6) with a hexagonal assembly hub (B), and 5 outer/inner struts (5)(6) with a pentagonal assembly hub (C) in 2 layers, wherein each strut has bevels (5d) (6d) on its both edges, and the outer/inner struts (5)(6) are of the same form except a transversal beam (7), and particularly the strut assembly set (A) is fixed by fastening it to the axial pillar (10) by tightening upper/lower fixing bolts (9')(9") inserted through the bolt opening (10') of the axial pillar (10) and then covering the upper/lower fastening parts of the axial pillar with a cover plate (12) and a packing (12a); each outer strut (5), a component forming the strut assembly set (A), has a pair of protruded prop plates (5c) beneath its mid part and a groove (5e) formed between them, into which each of packing insertion mounts (5')(5") is inserted from its both ends, and each outer strut (5) is formed by inserting each of packing insertion mounts (5')(5") having the inserted outer packings (5a)(5b) into the groove (5e); each inner strut (6), which is coupled with the lower part of the strut assembly set, has also a pair of inner prop plates (7") protruded on its mid part and a groove (6c) formed between them, which receives the prop plate (5c), into which each of packing insertion mounts (6')(6") is inserted in its both sides, and each inner strut is assembled by inserting each of packing insertion mounts (6')(6") having the inserted inner packing (6a)(6b) into the groove (6c), having the transversal beam (7) with the bolt opening (7') and the bump insertion port (7a) formed beneath it; each of transparent panels or glass panels (11)(11') is inserted between packings (5a)(5b) (6a)(6b) of outer/inner struts, and thereby the packing, which is highly elastic and cushioned, responds to the thickness of the glass panel, and the transparent or glass panel (11)(11') is assembled so that its angle may be adjusted upward or downward to have water proof, sound-proof, moisture-proof and impact cushioning effects; a plural number of strut assembly sets (A) are assembled by inserting and tightening the transversal bolt (8) with the bolt bump (8") and the head opening (8') into the bolt opening (7') of the transversal beam (7) respectively at the upper end of the axial pillar (10), and the fixing bolt (9) is manually inserted through the head opening (8') and it is tightened and assembled into the bolt opening (10'), and the fixing bolt (9) is inserted through the head opening (8') of the transversal bolt (8) coupled with the strut assembly set (A) at the lower end of the axial pillar (10) so that it may be oppositely and vertically aligned with the bolt opening (10') of the axial pillar (10), and thereby the strut assembly set (A) is tightened, fastened and assembled to the axial pillar; upper/lower strut assembly sets (A) are oppositely fastened and assembled to upper/lower ends of the axial pillar (10) in 2 layers by tightening the transversal bolt (8) and the fixing bolt (9), respectively; a cylindrical structure is formed by assembling 12 sets of pentagonal assemblies (2); and each strut assembly set (A) is lengthwise (interval-wise) adjusted by tightening its transversal bolt (8) loosely or securely into its bolt opening (7'), and the glass landing surface is variably rolled according to its upward or downward changeable angle.
